Subject: RE: replacing X Window System !

Although one has to admit that working with remote X
terminals over a
SSH/WAN/VPN-connection is far from usefull, [...]
You can tunnel just about anything X11 over SSH/VPN/etc.; even things
like a whole desktop GUI; not just plain X terminals.

Did you actually do that? Starting Firefox over a 6 Mbit VPN takes about 3
minutes on a FAST machine. That´s not acceptable - our users want (almost)
immediate response to an application, to clicking and waiting 10 seconds
until the app is doing something.

this is due to the latency, not the speed (X by default requires many round-trips to startup). There is an extention that greatly reduces the number of round-trips nessasary, I'm willing to bet this will make a huge difference for your startup. Unfortunantly I don't remember what this is.

however the huge delays on startup don't translate into a general slowdown once the application is started.

yes, this is an add-on, but the way that X evolves is for new functionality to be initially available as an add-on, and then move into the core distribution.

There are two ways of constructing a software design. One way is to make it so simple that there are obviously no deficiencies. And the other way is to make it so complicated that there are no obvious deficiencies.
